Abstract
A field experiment was conducted for two rabi seasons (2019-20 & 2020-21) at Regional Agricultural Research Station, Nandyala, Andhra Pradesh to study biofertilizers of PSB and inorganic fetilizers on growth, yield and quality Chickpea crop for Kurnool district of Andhra Pradesh. Afetr two years of the study, Significantly highest available soil Nitrogen (188 kg ha-1), Phosphorous (66.9 kg ha-1) and Potassium (484 kg ha-1) were recorded in treatment T8 (100% RDF + PSB in liquid form). Significantly highest chickpea yield of 2156 kg ha-1 was recorded with T8 (100% RDF + PSB (liquid form), the lowest yield was recorded with control (1839 kg ha-1). However, this treatment yielded results comparable to all treatments except the control during the two rabi seasons of 2019-20 and 2020-21. The economic evaluation of biofertilizers and chemical fertilizers application in chickpea crop revealed that maximum net returns (Rs 1,02,675) and higher B: C ratio (3.45) were obtained with application of 50% RDF plus PSB application. The present study was done to study to evaluate the influence of bio fertilizers on growth and yield of chickpea.
